Suggestions?? (w/Repost)

I've been struggling with this one for a while now. Had problems with color casts, and it just seems flat to me. Would appreciate any suggestions to improve this. Thanks!

The first thing that struck me was the bed of the river being a very reddish brown color. Was that the actual color?

A couple of things you could try, Phil.
Try that Image Polish technique (USM: Amount-25; Radius-50; Threshold-0).

Or you can try playing with a Selective Color adjustment layer.
For example:
In Reds, I moved the Black slider left to around -10.
In Yellows, I moved the Magenta slider left to -24.
In Blues, I moved the Black slider to left to -15.

This is a real nice image worth 'developing' just a bit further.

The falls section looks good to me, maybe bring up the leaves a little. The top half just needs a little pop, and John's suggestions always work for me. It's a very nice image.

Hi Phil, with the upper 3rd, try isolating that area, then use the highlight slider in Curves and drag it to the right to taste. Should add a little pop to this already beautiful image. Is the colorcast in the whites? If so, try isolating white in selective color and adjusting the hue.

Always interesting hearing about everyone's different approaches to processing! Some things I'd try (I rely on Tony Kuyper's techniques a lot):
Selectively painting in some glow or Orton into the upper third
Some dodging of the background trees, maybe targeting just the light tones
Some very light dodging of the upper falls and canyon to help the eye get there from the lighter tones at the bottom and maybe help with the sense of depth

Have you considered cropping just above the falls, leaving only a small amount of yellow above the water? To me, there are almost two images here fighting for attention, and the bottoom 2/3 is by far the more compelling. Just a thought...

Thanks for the suggestions! I tried them all. Here is a slightly reworked version. The difference is subtle. Still not all that happy with it. Maybe I should start from scratch!

I like the changes you implemented here.
Where more 'pop' (for lack of a better word) needs to occur is in the group of trees in the upper left quadrant, IMO.
If that is even possible.

Thanks, John! On my calibrated monitor it look far better than it does here. Perhaps going to sRGB and jpeg mute the colors some. I think I'll keep working it.

I agree with John on the trees. The leaves on the trees on the right edge of the image are very vibrant while the ones on the left are fairly dull in comparison. I do like the composition quite a lot and it is certainly worth your efforts.

Also agree with John's analysis. The repost is indeed better, though, I'd say keep moving it in that direction!

Nothing I can really add here. Beautiful scene and I'm here to promote John's processing suggestions, not just for this image, but for any image.

Well, here's the latest version. Think its done....for now.

Hey, that looks pretty good to me, Phil. Stick a fork in it...
